The invention describes a method and an arrangement for writing to NV memories in a controller architecture, together with a corresponding computer program product and a corresponding computer-readable storage medium, which may be used in particular to speed up writing or programming processes in NV code memories of microcontrollers, such as for example smart card controllers. The cavities are supported by a frame located inside the inflatable body and press the trunk section outwards, forming a flat shape. The machine incorporates features for thermal control necessary for high performance single stage pressure amplification, and features for minimization of mechanical friction necessary to ensure functional viability. During the local mode, nonrequested user data are retrieved from the discs and placed into the buffer in anticipation of a future request for the nonrequested user data. By the thin film transistor device of the invention, not only the freedom of circuit design is increased, but also the circuit area of a TFT device occupied is reduced.
